Availability according to Countries or Regions:
Australia and Japan
Description:
The Omron HEM-7121 is an automatic blood pressure monitor. The accuracy of its blood pressure measurement technology has yet to be proven to MDR requirements. Blood pressure measurements are taken from the upper arm. It is intended for self-measurement and home use.
Assessment:
The technology used in the Omron HEM-7121, to measure blood pressure, has failed in a clinical validation study, in a general population, according to a recognised standard protocol, as published in a peer-reviewed publication. It has also been compared to a clinically validated device, but the results of the equivalence study have not been published and cannot be verified; nor can the protocol be checked for compliance with (EU) 2017/745 and MEDDEV 2.7/1 rev 4.
